I noticed that a lot of people think you need high accuracy tools to build a transistor, you dont, not if you are building a type of transistor that barely saw the light of day.

The first transistors made, were designed to replace the vacuum tube, and were huge, crude, inefficient, and ugly. But much better then vacuum tubes.

You could make one by hand using blacksmithing tools, if you know what materials to use. The hard part is you would need electricity, advances in material sciences and chemical engineering, in order to understand how make these crude transistors.

But the hardest part of all? Designing the low l even instruction set for your first 100 square meter computer would be a nightmare for one person to attempt. (Eniac was the brain child of two geniuses and a team of scientists)

Edit: I think some think I an referring to modern nanometer transistors made in integrated circuits and that i am claiming they are "easy" to make. I am not, as even with our practically pure silicon and germanium their are still tons of gates that fail due to impurity, hence why cpu companies sell cups that are practically identical to each other as different chips because they had to disable certain cores, due to gate failures.

But large centimeter size transistors are makeable by people in their backyard. You just need the right cookbook, a lot of time, and enough money to pay for your many, many failed attempts.

This is true of a lot chemistry though, because it's the recipe that is hard to discover, one the recipe is written down it becomes simple, hence why it took a genius to realize nitro glycerine could be stabilized by mixing with powdered shell or clay and some type of sorbent, but anyone who can read can easily figure out how to do it today.
